[This essay is part Q in my series, An A-Z of Unanswered Objections to Christianity on the crisis in Christian apologetics. Other parts completed to date:F. Angels, demons and aliens and H. Human Origins.]

The question I wish to discuss in this post is not “Is it true that Jesus was virginally conceived?” or even “Is it possible that Jesus was virginally conceived?” but “Is there any good evidence (historical, prophetic or otherwise) that Jesus was virginally conceived?” What I want to argue in today’s post is that even for someone who accepts the evidence for Jesus’ bodily resurrection, the evidence for Jesus’ virginal conception is unpersuasive and the arguments marshaled in support of it are riddled with fallacies.

I would like to make it clear at the outset that I am not asserting that Jesus was conceived naturally. Generations of Christians down the ages have drawn hope and inspiration from their belief that Jesus was born of the Virgin Mary, and who am I to contradict them? After all, I’m one of them. What I am questioning is not the belief itself, but the justification for treating it as an essential teaching of the faith, as the vast majority of Christians continue to do (e.g. Catholics, Orthodox Christians, Lutherans, Calvinists and “Evangelical Christians”). As far as I can tell, there is no rational justification for doing so, and any attempt to argue for the Virgin Birth is sheer foolishness. Treating the doctrine as a “hill to die on” can only damage the credibility of Christianity, because it turns every argument against the doctrine into an argument against Christianity. Here’s why I think we should at least listen to the doubters, and why Christians who choose to believe in Jesus’ virginal conception should do so tentatively, acknowledging that they might, after all, be mistaken.

As discussed here extensively, nothing in “evolution” makes any sense: “natural selection, fitness, speciation, human evolution, gradualism, divergence of character, UCD, TOL, etc. etc.” Not one makes sense. Meanwhile, the “evolution” argument is just one big “affirms the consequent” logical fallacy, while Paley’s excellent argument has never been overturned, and an intuitive intelligent design detector can be used to easily disprove “evolution”. Is there a need for any more proofs? Not really. Are there any other proofs? You bet. Take entropy for instance… Continue reading →

Background

For the past month or so I’ve been investigating the claim that the phylogenetic signal is evidence that a dataset shares common descent.

Supposedly, the phylogenetic signal is one of, if not the, strongest pieces of evidence for common descent. It is one of the first of the 29+ evidences for evolution offered over at Talk Origins (TO).

Quoting from the article:

The degree to which a given phylogeny displays a unique, well-supported, objective nested hierarchy can be rigorously quantified. Several different statistical tests have been developed for determining whether a phylogeny has a subjective or objective nested hierarchy, or whether a given nested hierarchy could have been generated by a chance process instead of a genealogical process (Swofford 1996, p. 504). These tests measure the degree of “cladistic hierarchical structure” (also known as the “phylogenetic signal”) in a phylogeny, and phylogenies based upon true genealogical processes give high values of hierarchical structure, whereas subjective phylogenies that have only apparent hierarchical structure (like a phylogeny of cars, for example) give low values (Archie 1989; Faith and Cranston 1991; Farris 1989; Felsenstein 1985; Hillis 1991; Hillis and Huelsenbeck 1992; Huelsenbeck et al. 2001; Klassen et al. 1991).

I’ve been skeptical of this claim. A tree is just one kind of directed acyclic graph (DAG), and my hunch is many kinds of DAGs will also score highly on metrics for phylogenetic signal. I picked one metric, the consistency index (CI), which according to Klassen 1991 is the most widely used metric. It also is the featured metric in the above TO article. Plus, it is very simple to calculate. So, I’ve focused my efforts on the CI metric. Continue reading →

Nonlin.org has a burning desire to discuss sexual selection. So, let’s.

The topic was tangential (though not entirely unrelated) to the evolutionary psychology thread. Nonlin was unable to restrain his contempt for his interlocutors, and so his final missive was guanoed. The opportunity to repost was declined, as guanoing is ‘censorship’ (in plain sight!) and a ‘white flag’ allowing nonlin to declare victory and strut around like … well … a peacock.

Let me begin with a confession. Temperamentally, I’m very much disposed to believing in angels – and aliens too, for that matter. I would certainly echo Hamlet’s famous saying, “There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy.” The notion that human beings are the most intelligent creatures in existence strikes me as a monstrous vanity.

Now, I don’t claim to know what other kinds of intelligences exist in our cosmos. But one thing I do know: both angels and aliens pose genuine conundrums for would-be defenders of the Christian faith. In a nutshell:

[For a brief explanation of my “An A-Z of Unanswered Objections to Christianity” series, and for the skeptical tone of this article, please see here. I’m starting my A-Z series with the letter H, and I’ll be zipping around the alphabet, in the coming weeks.]

In this article, I take aim at the Christian teaching that there was a special moment in history at which humans, who were made in the image of God, came into existence, and that a sharp line can be drawn between man and beast. I argue that on purely scientific grounds, it can be shown that such a view is highly unlikely. If the scientific arguments I put forward here are correct, then Christianity is in very big trouble.

The sinking of the Titanic, by Willy Stöwer, 1912.

During the past 25 years, there has been a dramatic resurgence in Christian apologetics, as many talented individuals have written books and given public speeches in defense of the Christian faith. Some of these people have even gone so far as to claim that we are now living in the Golden Age of Christian apologetics (see here, here and here). More books are being published than ever before, and the New Atheist movement, which appeared so powerful ten years ago, has largely fizzled out. The future looks good – or does it?

In this series, I’m going to explain in detail why I believe this rosy view is utterly mistaken, and why Christians are actually facing a thirty-year winter. Continue reading →
